Bought this Smith & Wesson yesterday in decent mechanical shape. Caliber is .32 S&W (added via edit). Can someone idendify the model/version and date range for me? I'm trying to figure out if this was made in the black powder or smokeless powder era. Numbers match but I thought it was odd that there wasn't a S&W emblem on the side of the frame. The only S&W marking is on the barrel with the patant dates. Serial number is 51,XXX. Sorry about the poor cell phone pictures, but hopefully they show enough detail for identification.
